Abstract: According to the invention, the section (2) comprises a double-sided adhesive strip (8) which is covered with a protective film (11). The aforementioned protective film (11) is removed by way of a pull tab (12) before gluing, the tab consisting of two tab parts (15) which are positioned on either side of a slit (16) in the film. The automated method comprises, in the extrusion line, a step whereby the pull tab (12) is joined to the adhesive-covering protective film in the middle of the adhesive area transversely to the section. The tab and the protective film are subsequently cut in order to produce two tab parts which are each connected to the end of one length of protective film (18) which is intended to be torn off. The invention is particularly suitable for use in the car industry and in building and for producers and users of extruded sections which are glued using double-sided adhesive.

Abstract: The invention relates to a gasket seal (1) in the form of a profile comprising a U-shaped groove (23), which is intended to claim the edge (9) of the window (3) and a flexible masking lip (25) which is used to conceal the gap (8) between the window and the body (5). The inventive seal also comprises a longitudinal rib (29) which is provided with local deformations (30) that act as positioners (17). The method of producing the aforementioned gasket seal comprises a step involving the extrusion of a profile which comprises a U-shaped groove, a flexible masking lip and a continuous longitudinal rib and, subsequently, a step whereby said rib is deformed locally in order to form the positioners. During said deformation step, the rib is flattened locally by a crushing or pinching in order to reduce the thickness thereof and increase the height of same in the relevant area. The invention is particularly suitable for manufactures of motor vehicle accessories.
